Ecosystem Basics

An ecosystem includes only the living organisms in an area.

Abiotic factors in an ecosystem include plants and animals.

Biotic factors are the living parts of an ecosystem.

A food web consists of multiple interconnected food chains.

Producers are organisms that make their own food through photosynthesis.

Decomposers break down dead matter and recycle nutrients back into the ecosystem.

Competition occurs when organisms of the same or different species compete for the same resources in an ecosystem.

Predators are organisms that are killed and eaten by other animals.

Abiotic factors like light and temperature have no impact on the types of organisms found in a habitat.

Humans can impact ecosystems through activities such as deforestation and pollution.

A decrease in the population of a prey species will not affect the population of its predator.

All ecosystems have the same abiotic and biotic factors.

Water is an essential abiotic factor for all living organisms.

Soil type and quality can influence the types of plants that grow in an ecosystem.

The presence of certain microorganisms can cause diseases that affect the health and survival of other organisms in an ecosystem.

In a food chain, energy flows from consumers to producers.

Animals that eat both plants and animals are called omnivores.

Light is not necessary for photosynthesis in plants.

All living things need oxygen for respiration.

A habitat is the place where an organism lives and finds the resources it needs to survive.
